摘　　要：为厘清安徽农业面源污染现状,针对性地制定面源污染控制措施,运用污染清单、污染排放强度等方法分析了安徽农业面源污染负荷及空间分布特征。结果表明:2016年安徽农业面源污染物排放总量为125.49万吨,农村生活是安徽农业面源污染的主要污染源,其次是畜禽养殖和水产养殖;安徽各地市污染物排放量存在明显差异;2016年安徽农业面源污染平均排放强度为95.16 kg/hm2;阜阳市、蚌埠市和淮南市为农业面源污染的高度敏感区和优先控制区,畜禽养殖是这些区域的重点污染源。因此,应优化畜禽养殖业布局、推广施用有机肥、降低水产养殖密度等,从源头上治理安徽农业面源污染。It was analyzed that the agricultural non-point source pollution load and spatial distribution characteristics,in order to clarify the status quo of agricultural non-point source pollution in Anhui Province,and specifically address agricultural non-point source pollution,based on the pollution list,pollution emission intensity.The results show that it was 1,249,900 tons in the total amount of agricultural nonpoint source pollutants in Anhui in 2016.The rural life was the main source of agricultural non-point source pollution for in Anhui,followed by livestock and poultry breeding and aquaculture.There is a significant difference in the discharge of pollutants in various cities in Anhui.It was 95.16 kg/hm^2 for the average emission intensity of agricultural non-point source pollution in Anhui in 2016.It is highly sensitive and priority areas for agricultural non-point source pollution in the Fuyang City,Bengbu City and Huainan City,which is the key pollution source of the livestock and poultry breeding in this area.Therefore,it should optimize the layout of the livestock and poultry husbandry,promote the use of organic fertilizers,and reduce the density of aquaculture.It has become an important measure for controlling agricultural non-point source pollution at the source.
